ROLLER ATTACHMENT FOR BREAST-STRAPS.

Specification forming part of Letters Patent No. 40,045, dated September 22, 1563.

To all 'whom it may concern Be it known that I, F. JONES, ot' Prescott, in the county ot' Pierce and State of Wisconsin, have invented a new and useful Roller Attachmentlior the Breast Straps of Double `Harness; and I do hereby declare that the followingis a full, clear. and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l is a section of my invention, taken in the line fr a', Fig. 2; Fig. 2, a side view of the same; Fig. 3, a perspective view of a breast-strap and neck-yoke, with my invention applied to it.

Similar letters ot' reference indicate corresponding parts in the several figures.

The object of this invention is to obtainV a simple means to prevent horses in double harness being shoulder-jammed, and also prevent the friction and rubbing on the shoulders of horses, caused by the lateral motion of the ordinary breast-straps, as well as to prevent the wear of the breaststraps caused by the rubbing ofthe same through the rings which connect them to the necleyokes.

To enable those skilled in the art to fully understand and construct my invention, I

will proceed to describe it.

A represents a frame, constructed of any suitable metal or other material, and formed with three sides-two of which, a c, are parallel with each other and the other one, a', which connects a a at right angles to the latter, as shown more particularly in Fig. 2.

To the center of the side a of the frame A there is a hook, b, and between the outer parts of the sides a a there is ,tted a roller, B, which is of metal or other material, and provided at each end with a circular ange, c, the inner surfaces of which are beveled or rounded, as shown clearly in Fig. 2. This roller is provided at each end with a journal fitted in the sides a a, so as to turn freely therein, or a shaft may be secured between the outer parts ot' the sides a a and the roller B itted loosely upon it.

ln the inner surface ot each side piece a there is made a recess, d, to receive the edges ot' the flanges c ofthe roller, as is also shown clearly in Fig. 2.

The invention is applied and used as follows: The hooks b are ltted in the rings at the ends of the neck-yoke, the latter being attached to the end ofthe draft-pole, as usual, (see Fig. 3,) and the breast-straps pass around the roller B and are attached to the haines ot' the collars, as usual. The rollers B, it will be seen, admit of the breast straps working freely. preventing,` the straps from being chat'ed and worn, and also preventing shoulder rubbing or jamming caused by the old'mode of attachment, which does not admit of the free working ot' the breast straps.

By having the flanges c of the rollers fitted in the recesses d in the inner surfaces of the sides a a of the frames A, the breast-straps are prevented from catching on the edges of the tlanges and a free movement allowed the former in all cases or at all times.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The frame A, provided with the roller B and the hook b, when applied to the neck-yoke and breast-straps, substantially as and for the purpose specified.

F. JONES.
